PEHR JOSEF JONSSON, or STOCKHOLM, SWEDEN. AVENDINei-NIA'Ci-iINE.v l i l n T all whom it may concern:

Be it knownthat I, ERIK CLAES JANSON, mounter, a subject' ofthe King of Sweden and Norway, residing in Stockholm, Sweden, 5J haveinvented certain new and useful Improvements yin Vendin -Machines, of which the following is a speci lcation. This invention relates to coin-controlled vending-machines, and has for its principal ro object to'provide a mechanism of simple construction which may be operated on the insertion of a coin and without any subsequent manipulation for the purpose of opening or lotherwise moving the deliver -door or the x5 like, so that access may be ha to the article purchased, f

` A further object of the invention isto provide an apparatus having a door or shutter which may bev moved to open position on the ge insertion. of a coin and is so balanced when closed that its weight will not interfere'with the operation of the coinloontrolledniech# amsm. A f

A still further object oi' the invention is to z 5 providean apparatus of' this type lin which the parts may be readily adjusted tooperai tive positionby the simple closing of the door orshutt'er.

With these and other objects in view, as- 30' will more VJfully hereinafterl a pear, the invention consists in certain novelfeatures of construction and arran ement of parts hereinar`v ter fully described, illustrated'in the accompanyingv drawings, and' particularly pointed 3 5 out in the appended claims, itheing understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sac'riiicing any'ofthe advantages 4o of theinvention.

In the accompanying drawings, Figure 1 is asectional elevation of a portion of a vending-machine, illustrating a coin-controlled mechanism constructed in'accordance with 45 the invention. Fig. 2 is a similar view showing the parts inj the positions assumed after ,the insertion of a coin. Fig. 3 is a sectional plan view through a portion of the casing,- showing the mounting of the delivery-door or 5o shutter. "L l f 'Y Si I- lar numerals of reference are employed to 'indicate correspondin parts throughout the several iigures of the rawings'.

A The apparatus forming the subject of the .Specication of Lettera Patent. AApplication tiled August 21,1905. Serial No. 275.13m

is notched to form 'shouldersthat engage' Patented July` 5 present invention is intended princibiiy for 55 use in connection with devices of tlatjclass wherein a casingA is provided with a mov;- able door or'shu'tter l which may be opened after the insertion of a coin for the purposejof obtaining access'to a revoluble carrier B,y on 6o whilch the articles exposed for salcarecar- In carrying out thel invention the doorfl is normally maintained in the vertical position shown in Fig. l, said door being mounted on 6 5 a ivot-pin 2, the ends of which are supporte by the casing. Projecting Jfrom the vopposite sides oi the door are inclined arri`1`s1 4,'. v which are projected, downwardly a`nd` f o1 v wardly ofthe pivot-pin 2 and are' connected 7o by a pivot 6. to the ends of an arcuate bar 5, i

said bar being arranged to extend across the kvertical plane of thel axis of the pivot-pin 2.r

The .inner central portion of this bar` `i s sup ported by a link 7, the lower end of'which is 75 pivoted on a pin 7 within the lower portion v of the casing, and said link is designed tol'su port the weight of the inner portion oft e varcuatebar 5, so that the door 1 will be evenly balanced and` will tend to remain in the 'ver- 8o tical closed position. i

Within the lower portion of the casing is arranged-ja standard 20, to which is pivoted af coin-actuated bar 10,'the front 'end ofthe liar'4 bein curved upward slightly'andbeing 'diss -85 pose lbelow the bottom of a coin-chute 13 in position to receive the weight and impact. of de osited coins, and this end of the bar isp'ro vi ed with side'guards 2l in order to prevent lateral discharge ofthe coin, the latter bein 9e compelled to pass below' a slightly-incline iront arm 22, that extendsfrm the forward edge oi' the lower portion of the cojn-chute,l

The rear end of the bar 10 is provided with a coun'tcrbalancing-weight 28, which may be 9 5 adjusted in accordance with the weigj; of the coin to be used in operating the mac fe, and

-the bar must be so balanced thatfwhenfits forward end is struck by a descending ci'n it wil` be tilted down from the position sho in Fig. l'to that-illustrated in Fig.H 2.

The upper portion of the bracketgZO carr s a pin,25, on which is mounted a two-armed. lockingflever 9, the lowerand heavier arm of 'whichV is arranged to engage with a shoulder ro 5.

26', formed on the upper e geof the coin-enf-,g` f gaged bar 10. The upper arm of the lever y9 With the poincd end oll a bearing :zg-ainsi im tends to hold luc pa l'ioill lince olthis lilik, wl in engagement with said shoulder \io\'cnn-nt ol' tile lever .l in one dircction'is` limited by a slop-pin lll, and i; spring I4 Iends` to more .said lever in the opposite direction l'or lhc purpose olA mainlrii-tional engagei taining'its lower end in ment with the lshoulder 2o. This spring l-l is secured at on(l end lo a pivot-pin 125 and at its opposite end bears against the forward side ol a pin l5. projecting from the pawl N, said springr serving also asa meansl'or maintaining the pawl in engagement with the .shoulder ol the lever.

'ith the parts in the position shown in Fig. i it will be seen thaty the spring ll tends to thrnst th(l link 7 to th(` rear; but its movementy is resisted b v engagement ol the pawl 8 with the shoulder at the upper end ol the lever Sl and th(l force exerted by thespring is transmitted through this lever to the shoulder 26 ol' the coin-engaged bar 10 these parts heilig balanced and the movable door being maintained in its vertical closediposition.

When a coin is inserted in the chute 13, it falls intoengagmnent with the bar it), and the weight and impact ol' the coin moves said bar down until the shoulder 26 is free of the lever 9, whereupon said lever is turned from the position shown in Fig. l to that illustrated in Fig. 2 by means of the springs 14 and 11, the link 7 being thrust to the rear and forcing the door ltoopen position, so that access may be had to one of the compartments of the vending-platform B. v

The platform is then turned in the usual manner in lorder to restore the door to its closed position, whereupon the spring 14 moves the lever t) to the position shownJn Fig. l and the latter again enga l'es with the shoulder' i() ol' the coin-f 'ituated iar.

l claim-- 1` ln apparatus of the class described, the com bination. with a movable door, of a spring# actuated link serving as a door-opening pawl F tl1at is pivmeans, mechanism otallvcomici-lcd lo i ne link T. and a spring l l,

door, a coin-chute, a epm-actuated bar having one end adjacent to the bottom of the chute, a pivotallv-monnted lever having one end engaging said bar, and a pawl carried by .the link and arranged to engage the opposite end of said lever.

2. In mechanism of the class described, the combination with -a pivotaIly-mounted door, of a spring-atuated link for opening said door, a coin-chute, a eoinactuated bar having one end adjacent to the bottom ofthe chute and provide l with a catch-shoulder, a pivotally-mountei lever, the lower arm of which engages such shoulder, a pawl carried bv the linkand engaging the upper arm of Isaid lever, and a spring extending between the lever and pawl and serving to transmit movement from the pawl to the lever as the door is moved to closed position.

3. in apparatus 0f the class described, the combination with a vertically-swinging door normally maintained in closed position, of forwardly and downwardly extending arms projecting from the pivot-point of the door, an arcuate bar connecting said arm, a link having one end connected to a fixed point, and the other end to said bar, a spring acting on the link and tending to move the door to open position, a pawl carried by said link and provided with a projecting pin, a coin-chute, a coin-actuated bar having one end adjacent the bottom of the chute, said bar having a catch, a pivoted lever, the upper arm of which is shouldered, and its lower arm being arranged to engage the shoulder of the coinactuated bar, said paw] normally engaging the shouldered end of the lever, and a spring extending between the lever and the pawlpin', substantially as specified.

In testimony that l claim the foregoing as my own I have hereto aiiixed my signature in the presence of two witnesses.
